I don't know how to simplify the following functions (I get the asnwer right, but I don't know the steps!)
f(x) = 4x^2 - 12x / x^2 + x - 12
Please e-mail me: Katiewallin86@yahoo.c0m if you can help me with a few more problems, too. Thanks so much!
The top can be factored into 4X(X - 3), while the bottom simplifies to
(X + 4)(X - 3). The (X - 3) terms cancel each other out, leaving you with
4X/(X + 4).
I hope this helps. Thanks for asking.
